sufficient stock coverage - map and standard price
I a bit confused of the term sufficient stock coverage.
Say there is additional cost.
1) for material based on standard, whether sufficient or not, also will post to price difference. so this is not applicable to standard. correct?
2) for material based on map, if sufficient stock coverage, will be inventorised and moved the price. if not fully sufficient stock coverage, partly covered, will move the price, then the balance will go to price difference? correct?
3) suffiicient stock coverage will base on what criteria? i can only think of same batch number, same plant, what else?
